在一个或多个类与其他类相比非常罕见的情况下,很可能会出现被称为“数据不平衡(imbalanced data)”的问题。的确,预测罕见事件(例如,贷款违约)通常会出现这类最具挑战性的问题。这种不平衡的数据问题是dataset shift的一个常见原因。 如上图,不平衡数据:不平衡问题常常是样本选择偏差引起的,不平衡程度的判断仅依赖...

Machine LearningManufacturingBenchmarkThe development of machine learning applications in manufacturing depends primarily on the availability of meaningful and reliable data. In this paper, we present the Center for industrial Productivity - Discrete Manufacturing Dataset (CiP-DMD), the first open-source ...
In addition, we performed an extensive evaluation of the dataset using state-of-the-art machine learning (ML) to analyse diagnostic performance. To ensure reproducibility25, the project scripts and settings are published in a code repository, see the code availability statement. Here, we have not...
Evaluation of Feature Selection Methods for Preserving Machine Learning Performance in the Presence of Temporal Dataset Shift in Clinical Medicine BackgroundTemporal dataset shift can cause degradation in model performance as discrepancies between training and deployment data grow over time. The prima... ...
Machine learning has been extensively applied in small molecule analysis to predict a wide range of molecular properties and processes including mass spectrometry fragmentation or chromatographic retention time. However, current approaches for retention time prediction lack sufficient accuracy due to limited ...
In multimodal assistant, where vision is also one of the input modalities, the identification of user intent becomes a challenging task as…
